In this study, considering the poor shielding effects of rare-earth zirconate ceramic materials on thermal radiation at high temperatures, LaMnO₃ with small polarons was added to La₂(Zr_0.7Ce_0.3)₂O₇ as an absorptive second phase to prepare La₂(Zr_0.7Ce_0.3)₂O₇/LaMnO₃ composite ceramics.

The La₂(Zr_0.7Ce_0.3)₂O₇/LaMnO₃ composite ceramics possessed a dual-phase structure comprising pyrochlore and perovskite, demonstrating uniform grain distribution and clear grain boundaries.

To understand the high-absorption mechanism of the La₂(Zr_0.7Ce_0.3)₂O₇/LaMnO₃ composite ceramic materials, a LaMnO₃ small-polaron-hopping model was established.

Results confirm Sm₂O₃'s role as a network modifier through non-bridging oxygen evolution and borate structural units' transformations. The addition of Sm₂O₃ resulted in decrease rigidity and strength of the glasses network and slightly decrease elastic modulus parameters. The dielectric properties of Sm₂O₃-doped glass composites are evaluated across frequency and temperature. With Sm₂O₃ doping, permittivity is reduced because of charge localization and low charge mobility. AC conductivity has a low frequency suppression due to strong bonding with Sm–O and a high frequency enhancement through the defect states for electronic hopping. Dielectric loss exhibits several relaxation peaks which shift with temperature and composition. Findings suggest that dielectric tuning for electronic applications can be achieved by balancing a slight decrease in permittivity with a significant reduction in dielectric loss and improved thermal stability.
